OIL COOLING SYSTEM FOR EXPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented Jan. 7, 1919.

Application filed February 12, 1918. Serial No. 216,711.

'Systems for Explosive-Engines, of which the following is a specification.

My invention relates to improvements in oil cooling systems for explosive engines, and has for its object the production of an arrangement of this character, through the medium of which the oil contained in the oil pan or crank case of an engine, will be kept cool and thus the temperature of the engine generally kept down.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side elevation of a conventional explosive engine such as is used in connection with automobiles, in conjunction with which is illustrated an oil cooling system embodying the invention, and

Fig. 2, a view similar to Fig. 1 illustrating a slightly modified form of construction.

The oil cooling system is designed for use especially in connection with explosive engines, such as is shown at 3, the invention comprising the arrangement in the oil pan 4 of the engine of a cooling coil 5, said coil being so arranged'that, when said pan is provided with the customary quantity of oil for proper lubrication of the engine when running, said coil will be immersed in the oil. The coil has exteriorly projecting ends 6 and 7. Said coil ends are connected in the water cooling system used in connection with the cylinders of the engine,

of the pump 8 of thecooling system of the engine. The pump 8, as will be readily understood, is adapted to force the water through a manifold 9 into the water jackets which surround the cylinders 10 of the engine, the water after circulating through said jackets passing through an outlet manifoldv 11, whence the same passes through a radiator 12 and return pipe 13 which carries the same back again to the pump 8. The end 7 of the coil 5 is connected, as seen, with the outlet manifold 11.

- With the construction set forth it will be seen that during operation of the engine, some of the water forced by the pump 8 toward the manifold 9 will pass through the pipe 6, thence through the coil 5 and thence through the end 7 of said coil into the manifold 11, the water thus introduced into said manifold mingling with the water from the .cooling jackets of the engine and passing along therewith through the radiator 12 and pipe 13 back to the pump 8. Thus, it will be seen, that with this arrangement the pump 8 will serve the double function of forcing the cooling medium through the water jackets of the cylinders of the engine and the cooling coil 5, with the result that the oil will be kept at a low temperature, thereby materially assisting in keeping the engine cool. In explosive engines in use at the present time, the oil becomes highly heated, and thus in lubricating the engine causes heating thereof. Manually operable valves 14 and 15 are interposed in the ends 6 and 7 of the coil 5 for controlling the flow of water therethrough. I

In the form shown in Fig. 2, the ends 6 and 7 of the cooling coil 5 are connected with the fuel supply pipe 16 of the engine just prior to the entrance of the same into the carbureter 1770f theengine. To control the flow of the liquid fuel with reference to the cooling coil 5, valves 18, 19 and 20 are provided, interposed respectively in the ends 6 and 7 of coil 5 and the supply pipe 16 just beyond the connection therewith of the coil end 6. With this arrangement it will be seen that, if desired, the liquid fuel flowing through the pipe 16, may be diverted downwardly through the cooling coil 5, this being accomplished by simply closing the valve 20 and opening the valves 18 and 19. When this is done it will be seen that the liquid fuel will serve to coolthe oil in the oil pan 4 of the engine, and at- .the same time said fuel will become heated and thus facilitate vaporization thereof as will be readily understood. Where it is not desired to divert the fuel through the coil 5, it is only necessary to close valves 18 and 19 and open the valve 20.

While I have illustrated and described the preferred forms of construction for carrying my inventlon 1nto effect, these are capable of variation and modification Without departing from the spirit of the lnvention. L-therefore, do not Wish to be limited to the precise details of construction set forth,

butdesire to avail myself of such variations and-modifications as comeWithin the scope of .the appended claims.

Having described my invention What I claim as new and desire to secure by Letters Patent is:

1. The combination With an engine having an oil pan and a cooling system cooperating with the cylinders thereof, said system including a pump for forcing the cooling medium therethrough, of a cooling coil arranged in said oil pan and having one end connected insaid cooling system just ahead of said pump and having its opposite end connected in said cooling system at the out- 1,29o,ass

let side of the engine cylinder, substantially as described. i I

2. The combination With an engine having an oil pan and a cooling system cooperating Withv the cylinders thereof, said system ineluding a pump for forcing the cooling medium therethrough, of a cooling coil arranged in said oil pan and having one end connected in said cooling system just ahead of said pump and having its opposite end a connected in said cooling system at the out let side of the engine cylinders; and control valves interposed in said coil adjacent the ends thereof, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing itnesses.
